I don't know. 25 years ago, I might have had the time to memorize a big, branching level - because I feel that's the only way to properly play a 2D game built around speed. These days, I crave spectacle and (somewhat) instant gratification, but I still want to control the game. These corridors might be a bit narrow, but it's probably the only way to run at 200 km/h and not smash into a wall every 3 seconds...
